There must be a reason all drag brakes are drums.
I assume that constant application on a disc will overheat and glaze the wee, tiny pads.
Without a stoker, you won't have two rear brake levers.
The drag brake would be operated with a friction thumb shifter.
I think there is a reason that all modern high-performance cars, motorcycles, and bicycles use disc brakes and not drums, and it is not the surface area of the pads. I have only ridden one bike with Sturmey-Archer drum brakes years ago, and I was not impressed. I know some trike riders like them. I haven't seen a tandem with a drum drag brake since the late 1980s, but I don't get out much.
